Mitsui branches into land-based trout farming

Japanese trader Mitsui is embarking on a venture that could eventually result in salmon trout being farmed across Asia in land-based tanks to meet soaring demand for the fish from lovers of sushi, reports The Asahi Shimbun.

Mitsui expects to acquire an 80-percent stake in a start-up company that has pioneered a seawater filtering system for fish farming.
